Description

  The present invention relates to a spraying device for spraying livestock manure to pastures and fields, and more particularly to a mechanical structure for improving the spraying condition on soil.

  Conventionally, cattle and horse manure is sprayed on pasture to be used as pasture fertilizer, or sprayed on the field to be used as soil compost.

  FIG. 9 shows a conventional example of such a manure spraying apparatus. Reference numeral 1 denotes a tractor as a tow vehicle, 2 a vacuum car storing livestock manure, and 3 a manure spraying device connected to the back of the vacuum car.

The conventional spraying device 3 includes a disk-like disk 5 for forming a groove on the surface of soil such as pasture or a field, and a manure discharge injector 6. The manure discharge injector 6 is disposed behind the disk 5 and discharges livestock manure at an appropriate flow rate into a groove opened by the disk 5. The livestock manure to be spread is generally in a state where the moisture content is high, that is, in a state where it is easily ejected from the discharge injector 6. In some cases, only urine excluding dung components is sprayed.
None

  The biggest problem with conventional devices was the bad smell after spraying manure. Since the conventional spraying device only pours livestock manure into the groove opened by the disk 5, the malodor of manure is directly released to the outside air. The problem could not be resolved after a certain number of days when the composition of manure changed.

  In addition, it should be noted that the conventional spraying device returns the livestock excrement, which is industrial waste, to the pastures and fields for effective use, but the depth of the soil excavated by the disk 5 is shallow, and the roots of the grass are It has not been cut completely. If the soil excavation depth is shallow, the grass roots remain. As a result, it has been pointed out that the composting effect of sprayed livestock manure does not give the expected result.

  In order to grow good grass and the like by giving natural compost, it is desirable to cut the grass roots once every few years, preferably every year. The conventional spraying device made grooves at a shallow depth without cutting the grass roots, and sprayed livestock manure there, so the growth improvement of grass and the like as expected was not seen.

  Accordingly, an object of the present invention is to increase the soil excavation depth so as to prevent bad odor accompanying manure dispersion and to grow good-quality grass.

  In order to achieve the above-mentioned object and to solve the problem, the livestock manure spraying device according to the present invention is provided with trace teeth that scrape the soil around the groove where the disk is opened, between the disk and the discharge injector. A roller for rolling the soil around the groove where the disk is opened is disposed behind the discharge injector.

  This livestock excrement spraying device has trace teeth that scrape the soil left in the groove around the groove immediately behind the disk that cuts the groove, so it remains in the groove even if the drilling depth by the disk becomes deep Soil can be reliably removed outside the trench. When the disk is excavated at a deep depth, grass roots cut in the ground tend to remain in the groove, but are removed from the groove together with the soil by the trace teeth.

  A roller is provided behind the discharge injector. The soil around the ditch where the livestock manure is put is rolled back by this roller and backfilled. As a result, the livestock manure in the ditch is capped with soil, and the bad looks and bad smell are greatly improved.

  According to the livestock manure spraying apparatus according to the present invention, the soil is backfilled by the roller, so that malodor associated with manure spraying can be prevented. Also, the trace teeth ensure the formation of the grooves, and the grass roots can also be removed outside the grooves, so that the soil can be excavated at a deep depth. Even if the roots of the grass in the ground are cut with a disk, the roots of the grass will not remain in the groove, and the groove will not become shallow. It is possible to grow good quality grass.

  FIG. 1 shows one embodiment of a livestock manure spraying apparatus according to the present invention. For example, the spraying device 10 is connected to the immediate rear of the tractor 1. The vacuum car 2 is connected to the rear of the spraying device 10.

  The reason why the vacuum car 2 is the rearmost is to make it easier for the driver of the tractor 1 to visually recognize the operating state of the spraying device 10 connected to the immediate rear side.

  The vacuum car 2 storing livestock manure feeds livestock manure into the distributor 11 of the spraying device 10 through the hose 9 from the discharge port 8 provided at an appropriate position. Adjustment of the delivery pressure at this time can be performed by a pump (not shown) provided in the vacuum car 2 or the distributor 11.

  As shown in FIG. 2, the spraying device 10 is provided with a disk 14 at the foremost position in the pulling direction by the tractor 1, and a trace tooth 15 is disposed immediately behind the disk 14. An injector 16 is provided, and a roller 17 is provided behind the injector 16. These are arranged in a straight line.

  For example, as shown in FIG. 3, a plurality of the spraying devices 10 are attached to the arms 12 that are spread left and right from a three-point hitch connected to the rear of the tractor 1. The vacuum car 2 is towed by being connected to a tow hitch of a tractor, for example. The livestock manure sent from the vacuum car 2 to the distributor 11 is sent to the discharge injector 16 of each spraying device 10 via the hose 9 (see FIG. 1). The amount of livestock manure discharged from the discharge injector 16 to the outside is adjusted by, for example, the distributor 11.

  Next, the configuration of each unit will be described.

  The disk 14 rotates freely as it is pulled by the tractor 1 and advances while digging the soil.

  For example, as shown in FIG. 4, the disk 14 has a cutting edge 14-2 having a sharp tip 14-1 and a slightly expanding cross section toward the center. 14-3 is the surface excavation part which expands the soil surface to excavate and makes a big opening. A flat plate may be used for the central portion 14-4 of the disk 14. This is because the central portion 14-4 does not participate in soil excavation.

  It is desirable that the excavation of the soil by the disk 14 is performed at a depth at which the surface excavation unit 14-3 having a wide left and right width is used. The left-right width of the surface excavation part 14-3 is preferably 3 to 4 cm, for example. The excavation depth H is 5 to 10 cm, for example. If the tip 14-1 of the disk 14 enters into such a depth, the grass root can be cut almost certainly.

  Trace teeth 15 arranged in the immediate rear of the disk 14 push the groove hole excavated by the disk 14. As shown in FIG. 5, a groove P is formed on the soil surface by the rotation of the disk 14, but the excavated soil D is fragile and grass roots often remain in the groove P. The trace teeth 15 scrape the soil and grass remaining in the slot P out of the groove.

  The trace tooth 15 is preferably a single tooth having a lateral width comparable to the teeth (14-1, 14-2, 14-3) of the disk 14 or a single tooth slightly wider. There is no need for multiple teeth like a bear or an agricultural fork. It is desirable to set the depth to the soil substantially the same as that of the disk 14. It is desirable to use a plate that is sharp at the tip and slightly spreads upward and has a surface with substantially the same curvature as the disk 14. If the surface facing the disk 14 is curved, the grass roots can be effectively discharged out of the groove during tracing.

  As shown in FIG. 6, the discharge injector 16 fills the livestock manure R in the slot P. A conventionally known discharge injector 16 can be used.

  As shown in FIG. 7, the roller 17 provided behind the discharge injector 16 crushes the soil and grass roots scraped to the soil surface when creating the slot P, and opens the slot P as shown in FIG. The lid is formed.

  It is desirable that the roller 17 is configured to be able to move up and down flexibly with respect to the unevenness using a coil spring or the like. If the roller 17 can be moved up and down without using a spring, the soil and grass roots on the soil surface can be rolled by the weight of the roller 17 itself. The use of a spring has the advantage of avoiding poor vertical movement caused by clogging of soil and grass roots. The width of the roller 17 is set wider than the opening of the slot P so that the soil and grass roots scraped to the soil surface can be rolled.

  Therefore, according to the spreader 10, since the slot P is excavated by the disk 14 and the trace teeth 15, it is possible to dig deeper in the soil than before and cut the grass roots, and to cultivate high quality grass and the like. A possible soil environment can be created.

  In addition, after filling livestock manure R into the slot P, the soil by the roller 17 can be crushed to form a soil lid on the surface opening of the slot P. Can be prevented. It can also improve the appearance.

  Since the slot P can be formed deeply, the amount of manure filling per unit area increases. As a result, there is also an advantage that livestock manure that had to be disposed of as industrial waste can be effectively used as a soil improvement material.

  In addition, since there is no grass root when spraying to the field, cutting resistance by the disk 14 is small, and cutting by increasing the size of the trace teeth 15 is possible. Even when the amount of manure is applied, the shape of the disk 14 and the trace teeth By changing the 15 shapes, it can respond to various sites. In this case, it is preferable to make the width of the trace teeth larger than the thickness of the disk. In the case of pasture, it is desirable that the width of the trace teeth 15 is substantially the same as that of the disk 14 to reduce the excavation resistance applied to the trace teeth 15. This is because there are pasture roots.

  The livestock manure spraying apparatus according to the present invention is not limited to the above embodiment. For example, the spraying device 10 may be connected to the back of the vacuum car 2 in the same manner as in the past.

  The disk 14 is shown by shrinking the cross-sectional shape of the cutting teeth (14-1, 14-2, 14-3) toward the outer periphery, but excavation is possible even if the cross-section has a uniform width. Practically, it is more efficient to keep the tip (outer end) sharp. As for the disk 14, it is desirable to use a rigid metal for at least the incisors (14-3) at the outer peripheral end. The whole may be formed of metal.

  The trace teeth 15 are used to scrape the soil and grass roots left in the slot P by excavation by the disk 14 and are preferably a single metal tooth so as to maintain rigidity. However, the trace tooth 15 is a comb in which a plurality of metal rods are assembled. The same effect can be obtained by using a tooth-like one. When the teeth are comb-shaped, the roots of the grass are entangled, but in this state, the same effect as that of a single metal tooth is exhibited, so this is not unusable. However, it is more advantageous to use one metal tooth in terms of rigidity and cost.

  The surface shape of the trace tooth 15 (the shape of the forward direction surface) need not be curved. Curving a gentle curve is more effective in eliminating grass roots and soils, but even if it is straight, it can be either straight or bent in the middle, and it can be bent in the middle. This contributes to the formation of the slot P.

  The trace teeth 15 are preferably fixed objects that do not move up and down or left and right, but in places where there is a hard object (such as stone) in the soil, a spring material such as a coil spring or An elastic material such as rubber may be used to cope with the unevenness change.

  Since the discharge injector 16 is for filling livestock manure sent from the distributor 11 into the slot P, it is desirable to provide the discharge opening as low as possible. Since there are many undulations in the pastures and fields that serve as the work site, if you set it slightly higher (for example, 1 to 2 cm) from the soil surface, soil due to undulations or sudden changes in the traction behavior of trailer 1 Collision with the surface can be avoided.

  The roller 17 is desirably formed of a heavy metal. However, if the downward pressing force is sufficiently increased by using a coil spring or a leaf spring, it is possible to roll the soil and make a cover on the slot P even if a lightweight metal material or a resin material is used. The soil lid that closes the opening of the slot P need not be a lid pressed with a strong force, and may be a weak one that can prevent the odor of the livestock excrement R filled in the slot P from being scattered outside. This is because it is sufficiently effective. The roller 17 is fixed to a rotating arm urged downward by a spring, for example, so that the bottom surface thereof is always in contact with the soil surface, or disposed so as to be vertically movable through a slit.

  It is desirable that the arm 12 to which the spraying device 10 is attached be bendable at an appropriate place, for example, at a substantially intermediate position, so that it can be conveyed in a compact state. Even if the front portion is bent substantially vertically upward, a sufficient effect can be obtained.
